FILLER BLOCK FOR Application filed February 7, 1921.

1 '0 all whom it may concern..-

Be it known that I, Gnonen C. MURRAY, a citizen of the United States, residing at Chicago, in thecoun'ty of Cook and State of Illinois, have invented certain new and useful Improvements in Filler Blocks for Draft-Gear Yokes, of which the following is a specification.

This invention relates to filler blocks for draft gear yokes and its purpose is to provide an improved form of filler block and improved means for securing the filler block in the yoke. One object of the invention is to provide a filler block which is retained in the rear end of the yoke without increasing the total width of the yoke construction. A further object is to provide a filler block having flanges adapted to grip the tapered surfaces of the rear end of the yoke. Still another object is to provide a filler block which is welded to the rear end of the yoke and held in position without other fastening means. Other objects relate to various features of construction and arrangement which will be set out more fully hereinafter.

The nature of the invention will be understood from the following specification taken in connection with the accompanying drawings in which two embodiments are illustrated.

In the drawings Figure 1 shows a side elevation of a draft gear yoke with one form of my improved filler block mounted therein;

Fig. 2 shows a top plan View of the device illustrated in Fig. 1;

Fig. 3 shows a longitudinal sectional view on the line 33 of Fig. 1;

Fig. 4 shows a side elevation of the rear end of a draft gear yoke, illustrating another form of the invention; and

Fig. 5 shows a horizontal sectional view on the line 5-5 of Fig. 1.

In the form illustrated in Figs. 1, 2 and 3, the yoke comprises upper and lower arms 10 and 11, respectively, which are united by an integral rear wall 12. These parts of the yoke may be formed of rolled steel, for example, the bar of rolled steel being bent to impart a curved form to the rear wall 12, and the upper and lower arms 10 and 1 being united to the forward end or head of the yoke which is not illustrated.

The rear part of the yoke is tapered rearwardly on its lateral sides as shown at 13, the metal of the yoke being thickened in the DRAFT-GEAR YOKES.

rear wall 12, so that the cross sectional area of the tapered portion is the same as that of the upper and lower arms 10 and 11, respectively, although the width of the rear wall is decreased. The filler block 15 is formed in two similar complementary parts 16 having vertical forward faces 17, and curved rear faces 18 adapted to coact with the inner curved surfaces of the rear wall 12 of the yoke. The lateral edges of the parts 16 of the filler block are provided with inclined flanges 19 which are adapted to coact with the tapered lateral surfaces of the rear wall 12. The sides of the-filler block are hollowed out as shown at 20, and the central webs 21 are united by rivets 22. After the parts of the filler block have been placed in position with the surfaces 17 extending vertically and with the flanges 19 ripping the inclined or tapered lateral faces of the rear wall of the yoke, the two parts of the filler block are riveted together and the block is then held securely in position. Due to the taper of the rear portion of the yoke and the construction of the filler block, the outer transverse dimension of the filler block is less than or not greater than the transverse dimension of the upper and lower walls 10 and 11. The yoke is thus permitted to move freely between the sills without damaging or loosening the filler block by the engagement thereof with the draft lugs or other parts of the car structure.

In Figs. 4 and 5 of the drawings, there is illustrated another form of the invention, wherein the yoke has upper and lower arms 25 and 26, respectively united by an integral rear wall 27 having a curved form. A

filler block 28 is adapted to be inserted be tween the upper and lower arms and with its curved surfaces 29 contacting with the inner curved surface of the rear wall 27. The forward surface of the filler block eX tends vertically and the sides of the filler block are hollowed out, as shown at 31, to decrease the weight and cost of manufacture. The rear wall 27 and the filler block 28 are of the same width as the upper and lower arms 25 and 26 of the yoke. Each of the lateral curved edges of the tiller block is scarfed, as shown at 32, between the points 38, and this portion of the block is rigidly secured to the rear wall of the yoke by spot welding or the like. This forms a simple and convenient method of forming a connection between the filler block and the yoke which is sufficient to withstand all of the strains to which the filler block is subjected.

Although certain forms of the invention have been shown and described for purposes of illustration, it will be understood that it may be constructed in various other forms without departing from the scope of the appended claims.

I claim:

1. The combination with a yoke, having arms and a tapered thickened rear end, of a filler block having flanges engaging said rear end, said flanges being constructed and arranged to lie between the planes defining the width of said arms.

2. In combination, a yoke provided with arms and a rear wall having its lateral edges converging rearwardly, and a filler block having parts overlapping and coacting with said converging edges, said parts being constructed and arranged to lie between the planes defining the width of said arms.

3. The combination with a yoke, having a rear wall provided with lateral tapered surfaces, of a filler block formed in two parts each having a flange adapted to coactwith one of said tapered surfaces.

41-. In combination, a yoke having a curved rear wall, and a filler block having curved surfaces to coact with the inner curved surfac of said rear wall, said filler block being divided vertically into two parts, each of said parts having a lateral flange overlapping the lateral edge of said rear wall.

5. In combination, a yoke having a curved rear wall, and a filler block having curved surfaces to coact with the inner curved surface of said rear wall, said filler block being divided vertically into two parts, each of said parts having a lateral flange overlapping the lateral edge of said rear wall, the lateral edges of said rear wall and said flanges being tapered rearwardly.

6. In combination, a yoke having a curved rear wall, and a filler block having curved surfaces to coact with the inner curved surface of. said rear wall, said filler block being divided vertically into two parts, each of said parts having a lateral flange overlapping the lateral edge of said rear wall, the lateral edges of said rear wall and said flanges being tapered rearwardly, the outer transverse dimension of said filler block being not greater than the transverse dimension of the arms of said yoke.

In testimony whereof, I have subscribed my name.

GEORGE C. MURRAY.
